Coming Out Age: 37

Story:

Wow...  Where do I start?
I was married 15 years to a man who was my bestfriend, my lover, my confidant. I had "experimented" 
with females a few times and had told my husband.  We joked around with the idea of finding ourselves 
a girlfriend, but it never happened.  We raised two kids to the ages of 2 and 6, then he died suddenly.
I've just fallen in love with a (young) woman, and find myself freaking out over it.  I've come out 
to my bestest friends and most of my family, but not my 7 year old boy, though I think he suspects 
something going on.....  Oh what to do?
